Method of making a textile web from which elastically stretchable diaper closures can be stamped

Номер: US20120152435A1
Автор: Marcus Schoenbeck
Принадлежит: NORDENIA DEUTSCHLAND GRONAU GMBH

A textile web from which elastically stretchable diaper closures can be stamped is made by first passing a pair of nonwoven textile webs longitudinally through a first laminating station at a predetermined first speed and inserting a plurality of longitudinally extending and transversely spaced strips of an elastic polymer between the webs at the first laminating station. This laminates the webs and strips together into an intermediate laminate having longitudinally extending zones where the webs are directly laminated to each other alternating with longitudinally extending stretch zones where the elastic strips are laminated between the webs. This intermediate laminate then passes through a second lamination station downstream of the first lamination station at a predetermined second speed smaller than the first predetermined speed. In the second lamination station respective inelastic strips are adhered to opposite faces of the intermediate laminate in the zones between the stretch zones.

Aspects of the methods according to the present disclosure relate to the fabrication of diaper pants wherein discrete chassis are advanced in a machine direction such that the longitudinal axis is parallel with the machine direction. Discrete lengths of elastic belt materials are then connected with the first waist region of a first advancing chassis and the second waist region of a second advancing chassis. The lengths of elastic belt materials are cut along the cross-direction between the discrete chassis forming a first elastic belt and a second elastic belt; the chassis are subsequently folded; and the first and second elastic belts disposed on the chassis are bonded together to create a discrete diaper pant. This apparatus and process configuration forms a continuous web of articles formed by intermittently spaced chassis and intermittently spaced elastic belts bridging the gap between the intermittently spaced chassis. 1.

Apparatus and method for applying discrete components of a first substrate to a second substrate includes a programmable servo motor having a shaft. The servo motor is programmed to rotate the shaft in a first phase and a second phase at a variable angular velocity in a single direction. The apparatus also includes a crank member connected with the shaft, a connector link connected with the crank member, and a tamper member connected with the connector link. When the shaft rotates in the first phase, the tamper member travels from a first position to a second position to displace a selected portion of the second substrate into contact with the discrete component.

A disposable product comprising: a first waist edge located ahead of the absorbent core; and', 'a second waist edge located behind the absorbent core;, 'a chassis web having an absorbent core and comprisinga pair of opposing front wings coupled to the chassis web inboard and adjacent to a first side of each waist edge;a pair of opposing rear wings coupled to the chassis web inboard and adjacent to a side opposite the first side of each waist edge;an ear coupled to each rear wing at an outboard edge of each rear wing; andwherein each ear comprises a closure mechanism along less than a lengthwise direction dimension of each ear.2. The disposable product of claim 1 , wherein the opposing front wings are coupled to the chassis web in a mirrored orientation.3. The disposable product of claim 1 , wherein the opposing front wings comprise trapezoids.4. The disposable product of claim 3 , wherein an edge of each trapezoid forms a portion of a leg opening in each disposable product.5. The disposable product of claim 1 , wherein the opposing rear wings comprise trapezoids.6. The disposable product of claim 5 , wherein an edge of each trapezoid forms a portion of a leg opening in each disposable product.7. The disposable product of claim 1 , wherein the opposing front wings and the opposing rear wings comprise trapezoids.8. The disposable product of claim 7 , wherein an edge of each trapezoid forms a portion of a leg opening in each disposable product.9. The disposable product of claim 1 , wherein the chassis web comprises a continuous web.10. A method of manufacturing a disposable product comprising: ...

The present invention provides a method and apparatus for increasing the number of articles processed. over a distance traveled in the machine direction of an assembly line. In particular, the orientation of the long dimension of the article is provided transverse to the machine direction, thus process rug the articles side-by-side instead of end-to-end. 1. A method of producing a disposable product , the method comprising:coupling a first wing component to a first side of a topsheet web of material traveling in a machine direction;coupling a second wing component to the first side of the topsheet web of material adjacently to the first wing component in the machine direction;coupling a first base release paper to the first wing component; andcoupling a second base release paper to the second wing component and to the first base release paper.2. The method of further comprising:coupling an absorbent core to a backsheet web of material traveling in the machine direction; andcoupling the topsheet web of material to the backsheet web of material, wherein the absorbent core is positioned between the topsheet and the backsheet.3. The method of further comprising severing the topsheet web of material to create a discrete disposable product comprising the first and second wing components overlying the absorbent core.4. The method of claim of claim 2 , wherein the absorbent core has a length dimension and a width dimension less than said length dimension claim 2 , wherein the length dimension is oriented transversely to the machine direction.5. The method of further comprising releasably coupling a backsheet release paper to an underside of the backsheet web.6. A method of making a disposable product claim 1 , the method comprising:coupling a plurality of wings to a top side of a topsheet web traveling in a machine direction;releasably coupling a first release paper to a first edge portion of a first wing of the plurality of wings; andreleasably coupling a second release ...
